FilterRecords

This module does not take any input and does not produce any output.
It is intended to be used in the Pablo Execution Graph to filter
out record types which are not of interest to "downstream" modules.

During the configuration phase you can choose to copy through only 
records of interest, while discarding all other record types.   
This potentially saves considerable time during graph execution as 
uninteresting records need not be copied to or processed by multiple 
graph modules.
